Security audit

NinjaPear

Security checks for vulnerabilities and agentic risk

Overview

The NinjaPear searches fit the stated purpose, but the automatic setup can execute unverified software without a clear approval step.

Review and install a verified CLI release separately before using this skill, and check its automatic skill-synchronization settings. Requests use your OOMOL-connected NinjaPear account and may consume service credit. The remote installers could not be inspected, so their exact local changes remain unknown. The Review verdict concerns setup control, not evidence of malicious intent.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk installs software from cli.oomol.com rather than searching or reading NinjaPear data. Nothing in the provided content establishes this installer as a supporting dependency for NinjaPear, so its remote-code execution is not accounted for by the declared purpose. The downloaded script's further behavior cannot be determined from this chunk.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into Bash executes mutable remote content without a separate integrity or authenticity check; the PowerShell alternative has the same weakness. A compromised distribution endpoint or malicious installer update could execute arbitrary code and access files or credentials available to the process, although the skill provides no evidence that such compromise has occurred.

Content

The fallback setup instructs the agent to execute downloaded installer scripts without warning about the system-integrity implications.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The missing-CLI fallback instructs the agent to install software by immediately executing a remote script, without explaining the local-system effects or requiring user approval. Although conditional and relevant to the skill's dependency, this expands a data-reading request into code execution with the agent process's permissions.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
